ARH document readers for reading and verifying Passports, Visas and ID Cards
CLR desktop document reader
|Normal||Infra||UV||1.5 MPixel||3 MPixel|
The CLR 233 Full Page Passport Reader offers the highest level of travel document and personal identification document processing capabilities amongst the members of the new CLR family.
The CLR passport reader device captures the personal identification document, reads essential information from the captured image and forwards these information in ASCII to the host computer system.
There is also a possibility for automated authentication verification, so that the travel documents can be quickly verified with specific databases, checked against black lists, etc.
Besides OCR reading, traditional or two dimensional barcodes can also be read, and the integration of biometric identification is straightforward and easy.
True color images in as high resolution as 2048 x 1536 pixels are captured in three illuminations:
· normal light,
· infra red (IR) light of near 950nm, and
· ultra violet light (UV) of near 365nm.
Not only the resolution, but also the image quality is excellent, thanks to the most advanced digital image capturing technology of the CLR devices.
The excellent image quality and the high resolution provide unique document inspection possibilities, and a solid basis for automated travel document authentication through the smallest details of document security marks.
Image quality is a key issue. The digital imaging technology of CLR series is absolutely unique.
A different illumination (illumination in different wavelengths) does not only mean simply changing the source of light. Light of different wavelengths refract differently in the same optical system, the focal length of a lens has a dependence on the wavelength (color) of the light. The result: an optical system providing sharp images under illumination of normal light will result blurred images when applying IR illumination.
The CLR device automatically solves this problem!
Different illuminations also mean different digital camera settings (such as gain and white balance), which settings are all handled automatically by the CLR devices. The image quality is excellent in all available illumination due to the result of all the advanced technological solutions.
The size of the processed documents can be as large as 130mm*98mm, which allows processing of all passports worldwide. The image size is 1440*1088 (CLR 111, 121) and 2048*1536 pixels (CLR 223, 233), which results in a 250 and 380 DPI physical resolution. ( Note, that 200 DPI is considered to be excellent for OCR processing.) Each pixel of the captured image is represented by 3 bytes, a 24 bits RGB value.
After high quality images are captured from the document (passport, VISA, ID card, drivers' license, etc), the pictures in the memory have to be processed:
· the data from the card has to be read,
· the data reading has to be verified using CRC checks, and
· the authenticity of the document has to be verified.
